“…For example, Lu et al reported the one-step cathodic deposition of Co-BDC@CNH (carbon nanohorn) composite film for the detection of carbendazim in vegetables/fruits. 98 The deposition electrolyte was composed of 10 mM cobalt nitrate, 15 mM H 2 BDC, and 0.2 mg mL CNHs in DMF. When a negative potential of −1.3 V was applied to a GDE, the Zn-BDC film was cathodically deposited, while the positively charged CHN adsorbs on the MOF surface, forming a Co-BDC@CNH composite film.…”

“…MOFs can be made continuously and uniformly, the particle shape may be controlled, and there is a minimal solvent demand [ 77 ]. For the electrochemical detection of the insecticide carbendazim in samples of vegetables and fruits, Peng et al [ 106 ] used the electrodeposition approach to quickly and effectively produce a glassy carbon electrode covered with Co-MOFs and carbon nanohorns utilising 1,4-benzenedicarboxylic acid as the organic linker and Co(NO 3 ) 2 ·6H 2 O as the metal ion source.…”

Increasing trace levels of antibiotics and hormones in the environment and food samples are concerning and pose a threat. Opto-electrochemical sensors have received attention due to their low cost, portability, sensitivity, analytical performance, and ease of deployment in the field as compared to conventional expensive technologies that are time-consuming and require experienced professionals. Metal-organic frameworks (MOFs) with variable porosity, active functional sites, and fluorescence capacity are attractive materials for developing opto-electrochemical sensors. Herein, the insights into the capabilities of electrochemical and luminescent MOF sensors for detection and monitoring of antibiotics and hormones from various samples are critically reviewed. The detailed sensing mechanisms and detection limits of MOF sensors are addressed. The challenges, recent advances, and future directions for the development of stable, high-performance MOFs as commercially viable next-generation opto-electrochemical sensor materials for the detection and monitoring of diverse analytes are discussed.

“…Different carbon structures such as carbon spherical shells (CSS) [ 38 ], N-doped carbon (NC) [ 39 ], carbon nanofibers (CNFs) [ 40 , 41 , 42 ], porous carbon derivatives [ 43 , 44 ], carbon nanospheres (CNS) [ 45 ], and carbon nanohorns (CNH)s [ 46 ] have been used to develop electrochemical sensors for CBZ detection. Part of these materials allow LOD values below 1.0 nM with applications in food, water, and biological samples.…”

“…Among the electrochemical sensors developed for CBZ detection with other carbon materials, the lowest LOD value was reached by Peng et al [ 46 ]. The authors obtain a composite formed by the tremella-like co-metal organic framework (MOF) and carbon nanohorns (CNH) synthesized via a one-step electrochemical co-deposition technique.…”

Carbendazim, a fungicide widely used in agriculture, has been classified as a hazardous chemical by the World Health Organization due to its environmental persistence. It is prohibited in several countries; therefore, detecting it in food and environmental samples is highly necessary. A reliable, rapid, and low-cost method uses electrochemical sensors and biosensors, especially those modified with carbon-based materials with good analytical performance. In this review, we summarize the use of carbon-based electrochemical (bio)sensors for detecting carbendazim in environmental and food matrixes, with a particular interest in the role of carbon materials. Focus on publications between 2018 and 2023 that have been describing the use of carbon nanotubes, carbon nitride, graphene, and its derivatives, and carbon-based materials as modifiers, emphasizing the analytical performance obtained, such as linear range, detection limit, selectivity, and the matrix where the detection was applied.
